The article is confusingly worded. I think Google's announcement is more clear [1].
My read is:
* Developers using Google to process payments should expect to go from a 30% fee to a 25% fee (20% service fee + 5% billing fee).
* Subscriptions will now have a 15% fee (10% service fee + 5% billing fee)
* Some Third Party App Stores will be easier to install
